Address:  MOUND RD 
City & State:  MIAMISBURG  OH  45342
EPA ID:  OH6890008984
EPA Region:  05
NPL Status:  Currently on the Final NPL
ROD Type:  Record of Decision
ROD ID:  EPA/541/R-99/509
ROD Date:  03/15/1999
Operable Unit(s):  10
Abstract:  The Mound Plant Site was placed on the CERCLA National Priorities List (NPL) in 1989. The Department of Energy (DOE) signed a CERCLA Section 120 Federal Facility Agreement with the USEPA, effective October 1990. A similar tripartite agreement was signed among the DOE, USEPA, and Ohio Environmental Protection Agency (OEPA) in 1993. The Operable Unit 1 (OU1) Remedial Investigation/Feasibility Study (RI/FS) was conducted between 1991 and 1994 to identify the types, quantities, and locations of contaminants and to develop ways of addressing the contamination problems.
Remedy:  Institutional controls in the form of deed restrictions would be placed on Release Block (RB) D. The objective of these institutional controls would be to prevent an unacceptable risk to human health and the environment by restricting the use of RB D, including RB D soils, to that which is consistent with assumptions in the RB D Residual Risk Evaluation (RRE). DOE or its successors would retain the right and responsibility to monitor, maintain, and enforce these institutional controls. The institutional controls would:

- Ensure that industrial land use is maintained
- Prohibit the use of bedrock groundwater
- Provide site access for federal and state agencies for the purpose of taking response actions, including sampling and monitoring; and
- Prohibit removal of RB D soils from the Mound National Priorities List Facility boundary without approval from the Ohio Department of Health.

The soils within RB D have not been evaluated for any use other than on-site industrial use. Any off-site disposition of the RB D soil without proper handling, sampling, and management could create an unacceptable risk to off-site receptors. An objective of the preferred alternative is to prevent residential exposure to soils from RB D.
